Martinez, the Cowboys’ second-leading scorer, helped the team to a 12-0 start, but sat out the previous three games—prior to the suspension—with a broken ring finger on his right hand from the incident.

Martinez was arrested and charged with aggravated battery and assault in a Dec. 30 fight outside Buckhorn Bar in Laramie, Wyo., according to the Star-Tribune.

According to the police report, Martinez’s teammate Derek Cooke Jr. punched a man in the face and knocked him out. Then, as witnesses described in an affidavit, Martinez took “a running start” and kicked the unconscious victim in the head “like it was a football,” the newspaper reported.

Police said that Martinez “did verbally admit that he caused serious bodily injury to the victim knowingly or recklessly under circumstances manifesting extreme indifference to human life.”

The victim had to have his jaw wired shut after suffering “multiple fractures of the lower mandible” his brother said.

Martinez appeared in court Tuesday morning and will be released on $25,000 signature bond, the Star-Tribune reported. As part of his release, Martinez has to check in with the university’s athletic department three times per week, is not allowed to take drugs or drink alcohol, as well as not entering establishments “that make the majority of their income from sales of alcoholic beverages.”
